Some readers of the book have asked about the pictures in the book. One of the things they wanted to know was why the faces of some of the people in the pictures were obscured. Basically it was because you must have a person’s permission before you publish their image. This is something that must be done by a lawyer, and the editor’s advised me that it would not hurt the quality of the book if I protected privacy. I also wanted to reproduce newspaper headlines and photos in the book, but it involved so much extra work and expense that it was clear that I should use what was mine to use.
